I have had the same problem which also started a week ago or thereabouts. My government firewall blocks the ad also, but I have not been able to remove the virus ven with anti-malware programs...someone help!!

Since you're on a corporate network, the first thing I'd recommend is to chat with your IT department about the issue. If they're unable to resolve it, let me know, there are a few tools available that may do the trick.

Do you happen to have any anti-virus software running on your machine?

i'm getting the same behavior - tried scanning with malwarebytes, ms security essentials, AVG... nothing came up. I'm getting the spam links on Firefox, IE and Chrome. I'm home at the moment but will try to repro from the office tomorrow.

Same issue here, ran all the usual suspects which found nothing, just ran http://support.kaspersky.com/faq/?qid=208283363 (tds killer by kaspersky), select change paramaters and select 'detect TDLFS File system', this found and quarantined something which was then picked up by MS Sec Essentials as Trojan:Win32/Alureon.CT

Thanks for posting the Reddit link, there's a lot of good info there. As is mentioned in the thread, the redirect issue can sometimes be caused by an unwanted browser extension. I'd recommend disabling any unfamiliar extensions or add-ons and checking whether you're able to search normally again.

If that doesn't work, the problem is likely a bit deeper in your system. In addition to the software you've already tried, Hitman Pro is an option that many users have had success with. You can download it at http://www.surfright.nl/en/hitmanpro/.

Let me know if you need any help investigating extensions or running Hitman Pro and, either way, please let us know what you find.

Thanks for your suggestion and apologies for not acknowledging your earlier reply sooner. We use Symantec EndPoint as our corporate AV tool. I automatically run a full scan each week, and periodically run interim full scans as well. Our AV definitions are automatically downloaded from Symantec and pushed out to all our desktops as soon as they are received. In other words, we run a tight ship as far as AV tools are concerned.

My desktop support team ran Norton Power Eraser and CClean. Both did a good job of cleaning out a lot of low-risk malware and out-of-date registry entries. We also decrypted and reencrypted my system. Still, when I click on a Google search result, I am likely to be redirected to a googleads.i.net site, which we automatically block. However, if I highlight and copy the url listed under the search result link, I get to the right destination.

Given the lack of positive results that so many people with the same or similar problems have reported, I am beginning to suspect that the problem lies outside my system and instead, may be in Google's security infrastructure, especially in the malware protections for the AdSense and related programs. Is Google investigating to determine if internal vulnerabilities are causing this?

No worries about the delay -- I've been a bit behind as well. We're always working to make sure our systems are as safe and secure as possible, and we will continue to do so. In the meantime, there are a couple more tools you may want to try running. We hear from users that these are particularly effective at removing search-redirect style malware.

When making a google search on the name of my company (Company name: inordvativ, located in Denmark), you recieve some results that looks correct. By trying to follow the suggested links, sends you to a site in the .ru domain, that attemps to infect your computer. This is for sure a GOOGLE PROBLEM, since it happends on any computer and any device (iPads etc.). I tried to fine a contact to google to correct this, since it is important for our company. I could not find ANY contacts at all - VERY VERY frustrating!!!!!!
